This is included in the second release candidate for Bitcoin Core 0.20 linked in the preceding section. Also included are our regular sections describing updates to services and client software, new releases and release candidates, and notable changes to popular Bitcoin infrastructure software. With the above points we can see 2023 will see many crypto changes but the bullish market may continue. Here is where we arrive at the key constraints: There’s only so much computation modern hardware can perform per unit time - only so many signatures that can be verified and state changes verified. Congestion exists in a blockchain context because the basic security model of blockchains requires that end users can independently audit and verify the transactional history from the very first block should they choose to, and there’s a limit to the quantity of data that can be audited per unit time. ● Bitpay’s Copay and Bitcore projects support native segwit: Bitpay’s Copay wallet and backend Bitcore service both now support receiving to, and spending from, native segwit output

This week’s newsletter contains a warning about communicating with Bitcoin nodes using RPC over unencrypted connections, links to two new papers about creating fast multiparty ECDSA keys and signatures that could reduce transaction fees for multisig users, and lists some notable merges from popular Bitcoin infrastructure projects. Carlson says he and others will soon be scaling up so rapidly that, for farsighted miners, the Mid-Columbia Basin effectively is already maxed out, in part because the counties simply can’t build out power lines and infrastructure fast enough. Like the DCG agreement, Bitcoin Core’s scaling roadmap includes Segregated Witness as well. Although it’s already possible to refer to the key in those cases using the existing raw() descriptor, which is primarily meant to be used with tools like Bitcoin Core’s scantxoutset RPC for scanning its database of UTXOs, the new rawtr() descriptor makes it easier to use other existing descriptor fields to associate additional information with the taproot output such as key origin infor

So, the use of cryptocurrency is going to increase down the road. The conclusion: FTX wants to encourage users to use low-fee, less-energy-intensive, proof-of-stake blockchains. Conversely, at some point next year, Ethereum will move to a proof-of-stake model, at which point it will stop consuming meaningful amounts of energy. The per-transaction energy cost figure that FTX and the affiliated Solana make frequent reference to is not a useful analysis. They make it costly for information to be stored on the blockchain, thereby disincentivizing spam and DDoS attacks that have historically plagued zero-/low-fee networks, like Nano, EOS and XRP. Blockchain and Cryptocurrency go together like mac and cheese but also work fantastically on their own. Critics of proof of work might be tempted to claim that an increase in the interval between blocks affects settlement time, m.blog.naver.com which in turn increases congestion. Thus far, proof of work in high-fee environments is the only battle-tested mechanism known to the industry to be resilient against attacks. There simply is no inherent association between proof of work and high fees, or proof of stake and low fees. The reason that Solana, for instance, has low fees, is simply because the designers of that network were happy to adopt a different security model from Bitcoin or Et
um.
In Solana, there is virtually no difference between running a node for the purposes of verifying the integrity of the chain and running a node for mining blocks. All blockchains, including those that follow new architectures such as Solana, require users to wait before considering a transaction final. On such platforms, average transaction fees are quite high: around $2 per transaction for Bitcoin, and around $40 per transaction on Ethereum! But I expect Ethereum will still having meaningful fees at the base layer - and these fees will be considered desirable in many respects, since they support the deflationary mechanism introduced with EIP-1559. But these still represent genuine constraints grounded in the laws of physics. A PoS network could be completely costless from an energy perspective and constrict block space, causing fees to emerge; a PoW network could increase blockspace and drive fees to zero. Bitcoin could also process zero transactions per block, and miners would expend virtually the same amount of energy. Consider that a blockchain designed to produce one block per second with 1,000 transactions in each block has the very same throughput of a blockchain that produces one block per minute that is large enough to fit 60,000 transactions.
